Medical Xpress / Not all birth controls are equal, some are linked to higher risk of brain tumors, study finds
Meningiomas are the most common brain tumors in adults, accounting for 38% to 42% of all primary central nervous system tumors. According to 2021 WHO data, 874 million of the world's 1.9 billion women of reproductive age ...
Phys.org / Metallic rutile oxides break the rules of cooling
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...
Phys.org / Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy measure
Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, ...
Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Phys.org / Larger brain, smaller face: Human evolution took a different course than previously thought
A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size of the face and jaw—may be far less attributable ...
Phys.org / JWST finds the most distant barred galaxy candidate in the early universe
Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its ...
Phys.org / Baseline tool could separate alien life signals from geology on ocean worlds
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Phys.org / Scientists just measured the smallest possible contacts for future computer chips
The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their ...
Phys.org / How approaching sounds can warp your perception of time
Everyone's perception of time is unique. It is a subjective experience shaped by factors such as age, emotions, memory and environmental contexts. And it may also be influenced by background noise, as scientists have demonstrated ...
Phys.org / 'Cosmic wallflowers' may hold the key to the origin of globular clusters
Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...
Phys.org / Cave finds reveal modern humans and Neanderthals may have shared long-term cultural continuity
Tens of thousands of years ago, Homo sapiens coexisted with Neanderthals, Homo neanderthalensis. Many of us living today carry a small amount of Neanderthal DNA, indicating that the two species may have shared much more than ...
Medical Xpress / Brainstem neurons map whisker touch into object distance, reveals mouse study
If you are crossing an unfamiliar room in the dark, you may grope around a bit to get a sense of your space. But for many animals, feeling out a space comes more naturally. A mouse, for instance, can efficiently navigate ...
